BI-1347 是一种具有口服活性的、选择性和强效的CDK8抑制剂 (IC50=1.1 nM),且具有抗肿瘤活性。
生物活性 | BI-1347 is an orally active, selective and potentCDK8inhibitor (IC50=1.1 nM). BI-1347 shows anti-tumoral activity[1][2]. |
IC50& Target[1] | |
体外研究 (In Vitro) | BI-1347 (150 nM; 44 h) enhances granzyme B (GZMB+) production in mouse splenic NK cells[2]. BI-1347 (0.1 nM-10 μM; 24 h) treatment increases perforin secretion from NK92MI cells[2].
Western Blot Analysis[2] Cell Line: | Mouse splenic NK cells | Concentration: | 150 nM | Incubation Time: | 44 hours | Result: | Increased the proportion of granzyme B-positive NK cells by approximately 4-fold. |
Western Blot Analysis[2] Cell Line: | Human NK92MI cells | Concentration: | 0.1 nM-10 μM | Incubation Time: | 24 hours | Result: | Increased perforin levels with an EC50value of 7.2 nM. |

体内研究 (In Vivo) | BI-1347 (oral gavage; 10 mg/kg; once daily; 30 d) modulates STAT1S727phosphorylation and shows anti-tumor activity in vivo[2]. BI-1347 (oral gavage; 10 mg/kg) intermittent schedule and BI-8382 continuous treatment combination treatment increases efficacy compared to each monotherapy in the mammary carcinoma EMT6 model[2].
Animal Model: | B16-F10-luc2 syngeneic melanoma model[2] | Dosage: | 10 mg/kg | Administration: | Oral gavage; 10 mg/kg; once daily; 30 d | Result: | Reduced phosphorylation of STAT1S727for at least 6 h by 60%. Showed minimal effect on body weight at 10 mg/kg. Showed lower tumor burden both on day 23 and 29, compared to the control group. |
